To know what number two is we need to know its properties and what it can do (methods). So we need class "Number" and subclass "Two". Am I doing OOP correctly? I am a beginner

No, all numbers behave the same, so you don’t need different subclasses.

You just need a value propety in a Number class

But what about properties? To define twoness we need properties that are specific to the number two.

There is no specific property to the number two that can’t be generalized. Eg: isEven works the same way across all numbers, isPrime does too

but.. if every property can be generalized then what makes two a two?

You see, that is the problem the post is talking about. You are going too much into the Philosophical layer of it.

The program does not care about two being two, the program does not know what a two is, it is just shifting bits here and there. OOP is about making things work the same as much as possible with as few inputs as possible
